To connect only the corresponding points (without connecting any others) requires a loop —
LD1 = load('V_1.mat');
V_1 = LD1.V_1;
LD2 = load('V_2.mat');
V_2 = LD2.V_2;
figure
hold on
for k = 1:size(V_1,1)
plot3([V_1(k,1) V_2(k,1)], [V_1(k,2) V_2(k,2)], [V_1(k,3) V_2(k,3)], '.-')
end
hold off
grid on
view(60,15)
xlabel('X')
ylabel('Y')
zlabel('Z')
A scatter plot will not connect the points, so plot3 is required to draw the connecting lines. Choose whatever marker works best. I chose a small ‘dot’ marker here because the points are densely concentrated in part of the plot.
